Marwan Boustany, IHS senior analyst for MEMS & Sensors in Mobile and Consumer Technology, had some additional and insightful comments:
Most wearables previously relied on an accelerometer and pressure sensor to gauge distance traveled for calories, but A GPS chip that processes sensor data will make it possible to have a detailed record of both activity and distance, contrasted with wearables/smartwatches that use or display data from a handset. This will lead to a trend of more autonomy and local processing in wearable devices.
"As mobile processing gets more efficient and powerful (sensor hubs and generally low power processors), we will start to see wearables that rely less and less on a smartphone for sensor processing, location data and even conectivity," he wrote in an email exchange.
Boustany added that Broadcom's announcement is an expected technological advancement but shows a bright future for sensor hubs.
I am big fan of wearable and integrated devices but IMO the whole market is still not mature enough both in terms of technology and price. Mobile phone market has come a long way but i think the wearable devices will first be integrated in healthcare sector rather than in fashion market.
